TCM tune for five or six speed Allison transmissions.

When your truck comes from the factory the transmission calibration is less than ideally setup for optimal performance. Our transmission tunes for 2001 to 2015 Allison transmissions repair all of the short-comings in the factory transmission calibration.

2001 to 2010 Transmission calibrations focus on optimizing shift points based on the trubo(s) on your vehicle.

2011 to 2016 Transmission Calibrations will focus on optimizing shift points AND adjust commanded transmission line pressure to ensure that you are getting the correct pressure applied in each gear. This will ensure allow us to get the most out of your stock or aftermarket transmission and create shifts that are much firmer feeling.
